IMPROVEMENT IN WIR E-B AR BING MACHINES.

Specification forming part of Letters Patent No. 188,436, dated March13,1877; application filed October 25, 187 6.

To all whom it may concern:

Be it known that I, DANIEL (J. STOVER, of Freeport, Stephenson county,State of .Illinois, have invented new and useful Improvements inMachines for Put-ting Barbs on Wire, of which the following is a fulldescription, reference being had to the accompanying drawings, inwhich-- Figure 1 is a side'elevation; Fig. 2, a plan view; Fig. 3, arear view with the frame omitted; Fig. 4, a longitudinal verticalsection; Fig. 5, a front view with the frame and driving-wheels omitted;Fig. 6, details of the side hammers or plates.

The object of this invention is to apply barbs to all kinds of wire usedin making fences, firmly and expeditiously; and its nature consists infeeding the main or fence wireinto the machine at intervals; in feedingin a crosswire, from which the barbs are formed at the same intervals;in forcing the barbs tightly into position by a'series of hammer orslides; and in the several devices and combination of devices foroperating the parts hereinafter more fully described and claimed asnew.-

In the drawings, vA represents the main frame; B O, the head-block orframe; .D, the discharge opening; E, the platform; F, the guides; G, theslide; H, the tube through which the main wire passes; I, the pivotedblock to. Which the tube H is attached; J, the supports for the block I;K, the tube-guide; L, the lever for operating the slide G M, the bar orpitman for operating the lever L; N, the bearing-block; O P Q, thegear-wheels operating the feed of the crosswire from which the barbs areformed; R S, the guide-wheels for the barb-wire; T, the spur-wheel; T,the pin-wheel; U V W X, the gear-wheels; Y, the balance-wheel; Z, the

"main shaft; 0. a a b 12 b the guide-plate; c

the spring for returning the lever L; g, the

support for the bar M; r, the clamp on the I rear end of the tube H; s,the opening in the pivoted block I; t, the pin for rocking the tube 11;"a c, the cutter; w, the shoulders on the plates 6 f for setting thebarb; w, the holes in the plates 1 0 for holdingthe main wire'when thetube H returns; 3 the groove in the face of d, into which the main wireand barb are forced so as to form the barb vshaped.

The. frame-work A B .O and platform E may be made of iron, or partly ofiron and partly of wood. The head'B (3 may be-made of iron, and in anysuitable form for'supporting the parts which attach the barb. It isprovided with a central opening, D,-,large enough to pass the wire afterthe barbs are applied. Its rear face is furnished with guideplates 0. aa b b b for holding the sliding parts in position.

The sliding plates or hammers c d are each provided with a groove acrosstheir workingfaces, made sufficiently deep to take in near- 1y or quiteone-half of the main wire. The side plates orhammers cf are cut away atto, as shown, so as to pass over the main wire .and' bend the barb, andbring the shoulder up to themain wire, so as to firmly set the barbs inposition. These platesc d cf are operated by the cams or eccentrics g hz'j, which cams are operated from the gear-wheel X on the main shaft Z,through the wheels W V U,, as shown.

The platform E is provided with guideways F, between which the plate Gis operated.

This plate carries the tube H, through which the main wire passes, whichtube is pivoted by the block I to the supports J, so that the front endof the tube may rise and fall with- I in the limits of the opening K.The tube H is provided at its rear end with the eccentric or clamp T,which operates automatically, and

holds the wire for the purpose of feeding.- j

This wire passes under the guide-plate 'b, which may be sharpened at itslowerendat e, or a shear-blade may be attached thereto, so that when thehammer-plate d rises, the

wire will be severed at u with an angular cut, so as to give the barbssharp points.

This barb-wire is fed up at suitable intervals by means of thegear-wheels O P Q, which are operated by the spur or spoke wheel T andthe pin-wheel T, which advances the wheel T one step at each revolutionor complete operation of the devices for fastening hammers efarezgroovedon the top, soias to catch the ends of the barbs and carry them over tothe opposite sides. r y

The springs in 17, in the form shown, are

simply bent plates, used for returning the parts into position to beoperated upon by the eccentrics or .cams. This form will be foundconvenient; but, in practice, they may he made in any other suitableform which will accomplish the desired resultof returning the parts. 1

r In operation the main wire is passed through the tube H, with its endprojecting, out far enough to attach the first barb. The cross or barbwire is supported upon any suitable spool, which maybe detached from thema chine or attached thereto, as desired. Its end is passed between thegrooved wheels It S, and through the loop a. The machine is now readyfor starting. 1 i

In the first movement the tube H is advanced by the eccentric ispressing against the end of the rod M, which moves the lever L, causingthe plate G, with the tube H and appliances, to advance, so that theendof the tube comes up over the hammer-plate. d, and under the guidea.When this tube H has advanced about two-thirds of this distance,

the pinoriarm on the wheel T willcome in contact with one of the spursorarms of the.

wheel T, causing it to advance and, through the gear-wheels O P Q andgrooved wheels 1% S, force thecrossor barb wire forward un-. der themain wire the desired length forthe barb. In this position, with the endof the tube H over the barb-wire, as described, the

hammer-plate d rises bymeans of the co centric it coming in contact withthe lower end thereof, and the cross orbarb wire is severed at a bymeans of the cutter o. The main wire, with the barb, is then carried upby the continued rising of the plate (1, until the endofthe tube Hstrikes the lower end of the plate a, when the barb and wire areforcedinto the groove 3 on the face of the hammer-plate d, which causes the.barb to assume a V shape. Thenthe tube H recedes,

the main wire being held firmly between the end of th'e'plate l and thepart 0 of the hammer d in the holem. Then the sidelhamm'ers 6 fareforced forward, simultaneouslymby means of the cams ij coming incontactwith the outer ends of the hammer-plates, and the ends of the barb beingabove the points of the ha'mmersor plates e f, thesepoints will catchtheends of the barbs and cross them over to opposite sides, so as toencircle the main wire, ,and the shoulders to of these plates willstrike against.this encircling portion of the barb, and bring it inclose contact with the main wire, and force the barb ends at nearlyright angles therewith. Then these hammer-plates e f are released fromtheir contact with the cams i j, and will be returned to their firstposition by means of the spring m. The hammer orwplatec will now descendby meansot the eamgcoming in contact with the upper-end thereof, and,striking the barb ontop, will complete the fastening,and set the barbfirmly in position.

so that it will not move. Then the plates c at will be returned totheirfirstpositionsth-rough the springs m, leaving the main wire and'barb free to be passed through the opening D by the forward movement ofthe tube H, which 'takesplace as soon. as the hammer-plates c d arereturned. The hammers or plates e fare :so formed at their .pointsortinner ends that they will pass each-otheryso as to cross thebarb-wire, and :permit the shoulders 20 to come in eontactwiththeencirclingportion thereof. These hammers e f areyadvanced andreturnedsimultaneously, so thatwhen advanced they willact upon bothpoints of the barbat the same time,and thus .insureuthe proper coilingof the barb-wire around the main wire.- The hammer chatter it is raised,a will remain in that position, and serve the purpose of an anvil forthecompletion of the fastening by the hammerc. Both .of the hammers ad willreturn to position simulso that barbs will be applied atregular inter,

vals. By extending theguidect inward, as shown, the upward movement ofthe tube H islimited, so as to prevent :anybending or kinking of themain. wire while thebarbs are being fastened, and also to furnish ameans for forcing the barb into thegroove you :the

hammer clito form 'the vshape; but some other form ofstop might be usedfor this purpose.

It will be seen that by themethod herein described the turn or coil ofthebarbi around the main wire is firmly held against it,-so that whenthe blow or pressure from. the hammer or plate a is given, theeneirclingportion retainswits forn1,.without beingmade oval ordrivenawayat the sides, so that the coil is in the sliding plate G andlever L, for carrying the main wire forward, substantially as speci- 2.The tube H, in combination with the sliding plate G, lever L, pitman M,and cam or eccentric 70, substantially as described.
